" rllllljtltll darn lilo STATES hpplication filed Ltl'overnher 1925, Serial No. 67,871, in the Union or death .ditrica ileptcruher ll, will? This invention relates to machines or up paratus primarily designed tor concentratinp; the products or tinely crushed, ground or comminuted ores in order to separate the relatively heavy metalliterous particles from. the relatively lipght nonmetalliferous par ticles' thereof. The apparatus or machine can also he utilised for separating the metal" literous particles from other loose or reduced materials or alluvial deposits having a poet alliterous constituent, as well as for concentrating or separating a relatively heavy con stituent from an associated lighter constituent of any other similar mixture or asso ciation oi? materials.

The object oil the invention is to construct: machine or apparatus tor the purpose spect lied which will he simple in construction and inexpensive to manufacture; and one that will he elllcient and economical in operation.

The invention will he fully explained in conjunction with the accompanying sheet of drawinga wherein,

l is a part sectional elevation of the machine and i i Fig. 2 is a plan of the machine.

its illustrated in the drawings, the ma chine includes a pan or receptacle l in which the concentration of the crushed or ground ore or other material is eitected. The pan or receptacle l is combined with means tor impartinp; to it an irregular shalring or pan ninpg motion.

The concentrating pan or receptacle 1 is of inverted. conical shape in its lower portion 2, and of truncated conical shape in its upper portion 3. It is provided near the top with an outlet or delivery chute l for the ganguc, waste or lighter constituent, andv at the hottom, at or near the centre of the inverted conical lower portion 2, with a plurality-sin are shown-01. ring of discharge passages or openings 5 for the heavy nuterial or concentrates; certain of the paesa es or openings may, it desired, he closed, temporarily or otherwise hy means oi? removahle plugs. Th at portion of the hottoin oil the pan or receptacle 1. lying within the the ring ct passages or openings 5 may, as shown he raised and rounded or term portion ot a sphere, as indicated at '8, so that the concentrates will therehy he directed to the passages or openings ll. y

l" in Fig l represents a launder or trough. tor conducting the material. which is to he concentrated, together with a suitahle quantity oil water or other liquid, to the pan ll llpon the top of: the pan l trace is lined as by means of the hinged eyeholt-r-i an in verted conical. cover 9, which is constructed with a downwardly GItl'EllfllllQ; spout or tulnt lar extension 10 which entends to within a short distance oil the inverted conical hot-- tom 91 ot the pan l approximately midway hetwecn the wall oi? the upper portion El and the concentrates outlets ii. 'llhe parts 9, l0, serve as a tunnel tor receiving; the material troni the launder 'l' and. delivering it into the pan l at a suitohle point.

Tlhe pan fl is constructed in its lower portion with an annular errtension-or a mun-- her oi? l s or supportslh which serves tor lininoit by means ol set screws or holts 1% upon a carrying plate lth which is the means through which the irregular shalrinp' or panning motion imparted to the pan 1. In the plate 13 an opening ll provided havinga vertical discharge pipe l5 tor delivering the concentrates into any receptacle arranged hencath it to receive them. lll is a lined inclined any or chute tor receiving the concentrates a or they have passed through the passages 5 and delivering; the same to the dischz'irpge opening; l l-l l he pan l is opeiartively carried or supported hy a main :lrameworli: ll through the medium oil a ring or annular plate 18 'lhe carrier plate lI-l on the underside is construct ed to provide housings tor a plurality olt halls 19; 20 heinp; an annular recess in the hottoin ol the plate l3, and El a rinp; provided with a hole for each oi the halls lll and secured. to the underside oil the plate iltl hy screws PR. The several halls l9 are tree run in. con tact with the top ot the supporting rinn; ill.

The driving means tor the pan 1 includes a shalt 23 carried in hearings fi l, Elli. lined to cross menohers Elli, 927, oil the frame l'l'. field is a pulley on the outer end. oi shalt for driving; the same. tln the other and inner end oil the shalt Eli-l is fitted a hevcl pinion fill, which drives a turther hovel pinion Ell lined on a vertical cranlr shalt Ell. worlrinpj in a hearing 32 tired hetwcen the cross mctnhers E26, ill, of the :trame. a disc cranlt lined upon the upper end oil the cranlr shalt ill and 34; the cranl: pin which is vertical. and proie l into a hole tl orrned in. hose 8h provided on the underside ol. the carrier plate 13. lt will he understood that on mo tion heing imparted to the cranlr Elli, the cranlr pin E l causes the centre oil the pan t till lid

Eli

ltlll lllll llll to move in a circular path, the pan 1 then moving freely upon the bearings provided by the balls 19.

The pan 1 at one side is slidably connected to the frame 17 or a part fixed thereto in such a Way that, while it is free to be moved by the crank with its centre in a circular path, it isprevented from rotating about its own axis;

The means slidably connecting the pan 1 to the frame 17 includes a rod 36 fixed in the edge or rim of the carrier plate 13 and extending horizontally and radially from said carrier plate 13, a pivoted piece 37 which provides a sliding bearing for the rod 36, and a bracket 38 in the outer end of which the iece 37 is pivoted, said bracket being attached to the frame 17. \Vhen the circular motion is imparted to the centre of the carrier plate 13 by the crank pin 34:, the rod 36 is free to slide backwards and forwards through the bearing piece 37 and so precludes the rotation of the pan 1 about its own axis.

In the operation of the machine a whirling or whirlpool motion is set up in the contents of the pan or receptacle 1, which causes the heavy particles to collect centrally at the bottom of the pan whence they pass out throu h the passages or openings 5, while the lig liter constituent of the mixture, or gangue', and the associated liquid are discharged at the outlet provided by the delivery chute 4 near the top of the pan 1.

What I claim as my invention and desire to protect by Letters Patent is 1. A mineral concentrator, including a pan, means for introducing thereinto the material to be concentrated, an outlet for the lighter constituent of the mixture and as sociated liquid, means for withdrawing the concentrates from the bottom of the pan, a carrier plate for the pan, a supporting plate arranged below said carrier plate, balls arranged between said carrier and supporting plates, means engaging directly with the centre of the pan for causing the pan to move in a circular path, and means for preventing rotation of the pan about its own axis including a pivoted piece whose axis is fixed at some distance from the pan and means slidably connecting the side of the pan adjacent to the pivoted piece to said pivoted piece, as set forth.

2. A mineral concentrator, including a pan, means for introducing thereinto the material to be concentrated, an outlet for the lighter constituent of the mixture and associated liquid, means for withdrawing the concentrates from the bottom of the pan, :1 carrier plate for the pan, a supporting ring arran ed below said carrier plate, balls arrange between said carrier plate and supporting ring, means engaging directly with the centre of the pan for causing the pan to move in a circular path, said latter means including a crank the crank pin of which is adapted to engage with the carrier plate at the centre thereof, and means for preventing rotation of the pan about its own axis including a pivoted piece whose axis is fixed at some distance from the pan and means slidably connecting the side of the pan adjacent to the pivoted piece to said pivoted piece, as set forth.

In testimony whereof I have signed my name to this specification.
